Description
FIELD OF THE INVENTION.
[0001] The disposable speculum with included light and
complementary mechanisms for gynecological examination and surgery,
it is a medical instrument that gives positive advantage compared
with the other one which are used now in this health branch.
[0002] The vaginal speculum is a medical device, which is
introduced through the introito to the vagina separating its walls,
to be examined and making the medical or surgical proceedings
easier at the vaginas neck level by sight or guided by colposcopya
and of the uterus by the endoscopya.
[0003] The speculum upper sheet external face is convex, with flat
surface and rounded edges to avoid pinches, that happen frequently
using disposable speculas with sharp sides.
[0004] The internal face of the same sheet is concave and it has
three semicircular cuts with certain distance between them, and
they are connected amongst themselves for a pair of internal and
lateral channels, that end in the upper right part of the proximal
end which will serve to evacuate with a special vacuum (available
at the market), the smoke and gases generated when any sort of
gynecological surgery is practiced for vaginal tract, when
cauterius are used with mono or bipolar electrodes, radio frequency
or laser, this protects the medical doctor and close staff of
possible contamination, making the procedure easier and shorter,
because there is a better visibility.
[0005] The vertical branch or upper sheet handle has some prongs,
that insert in the vertical branch or lower sheet's handle, that
has some foremasts where the saw prongs will rest when the speculum
is open to make the visual and the examination area bigger. In
order to make the speculum opening smaller, it is necessary to
press on a button that makes the prongs come out and move away from
the foremast, sliding the upper sheet's vertical branch on the
lower sheet's vertical branch, and to close the specula and remove
it without pain, pressure has to be made on the other button to
unblock the upper sheet.
[0006] The lower sheet,s external face is convex with flat surface
and rounded edges, too. The internal face of the same sheet is
concave, and it has three semi-circulars cuts with certain distance
between them, connected amongst themselves for an internal oval
flat channel, which ends in the lower extreme of the sheet's
descendant branch, where it turns into a round channel where the
blood, that is originated from the surgical area through a vacuum
designed for this proceedings, is evacuated, making them more
comfortable easier and faster, avoiding the dryness and the
clearing of thief sloped place where the blood is accumulated. If
this end is not connected to a vacuum, it can also be connected to
make the blood flow through gravity. Joined to the previously
described, and to optimize the visibility of surgical and
examination area, in the upper sheet's internal face, in the
center, and on the space between the two first cuts, there is a
light bulb, which given its nearness to the surgical area, will
offer clarity and because of its localization will not interfere
with the surgical proceedings. The light bulb is protected to avoid
damage by the instrumental, and it has a thermal isolation to avoid
heat up of the speculum upper sheet, which would cause injuries on
the vaginal mucous. The internal face of the anterior portion close
to the light bulb has an aluminum reflexive cover (a metal covering
vacuum technique with aluminum) which will offer an excellent
lighting. The speculum has to be made of dark non-reflective
material when used in laser proceedings.
INVENTION BACKGROUND
[0007] Convinced by my personal experience as a gynecologist, that
many patients don't attend appointments of this specialty and don't
take a cytology, because they are afraid to be hurt when the
speculum is used; in some cases problems are created due to the
designs of some disposable speculum and reusable metal specula that
make their use difficult, not practical for the medical doctor and
uncomfortable for the patient, in many cases producing small
injuries that cause discomfort for the patients which give a bad
reputation to these devices.
[0008] The vaginal speculum is a device which is introduced through
the introito to the vagina separating its walls to be examined and
making the medical or surgical proceedings easier at the vaginas'
neck level by sight or guided by colposcopya and of the uterus by
the endoscopy
[0009] Some speculums have ungentle edges and their surface is
rough causing sometimes pinches of the vaginal mucous and on the
smaller and bigger lips. Others have their sheets separated which
makes them unstable when they are introduced in the vagina, causing
discomfort to the patients and not allowing the specula to open on
their distal end if it is required, to expand the surgery field and
examination area. Some of them have the handle's lower end of the
lower sheet with a forward curvature, being this the support point
to handle and open the speculum, which allows the contamination of
the gloves due to their closeness to the anal and perianal area,
besides to cause discomfort to the patients. The same happens with
the other ones that have a mechanism to open the sheet's that
consist in a curve piece with prongs on the upper sheet's handle,
which introduces itself in a cut of the lower sheet handle,
producing similar effect as the previous one. In both previous
cases if the medical doctor doesn't take precautions to change his
gloves and proceed to practice a vaginal tact like a complement of
the examination, he would be contaminating the patient with
possible anal pathology to the vaginal area, and with possibilities
of propagation to the pelvic area, with their consequences
sometimes irreversible from the medical point of view, like for
example, pelvic inflammatory chronic illness, infertility caused by
tubary obstruction among others and they seem expensive from the
economic point of view.
[0010] The speculum proposed by me, has rounded edges and fat
surface and has an opening mechanism comfortable and fast for the
upper sheet, the same works to enlarge the distance, between the
both sheets, giving wideness to the surgery or examination area.
The lower sheet's handle has in its distal end an elbow shaped
handle to avoid discomfort to the patients in the anal and perianal
area, and therefore with out contamination.
[0011] In regards to the portable lighting which come from the
light bulbs, which are located on the speculum upper sheet and
which after each examination are removed and used again with other
patients, open the possibility for contamination even with
precautions. The same would happen in other prototypes of reusable
lighting, where the light is attached to the upper sheet's internal
face with adhesives used for these cases.
[0012] The lighting proposed by me, would be included in the
disposable speculum upper sheet internal face through a small light
bulb localized between the two first cuts, and it will be feed
through a plug located on the back end and upper right of the
speculum upper sheet. The light bulb has a thermal isolation to
avoid injuries of the vaginal mucous membrane, and also because of
its proximity to the surgical area, it will give an excellent
lighting that will help to make the procedures easier. The internal
face in the front part at the light bulb has an aluminum reflexive
cover (aluminum metal vacuum technique) which will have effect on
an very good lighting. When the speculum is used in proceedings
with laser, it has to be made with a dark and no reflexive
material.
[0013] There is a pipe system for the smoke and gases suction which
are generated in specific gynecological methods through vaginal
via, but its surface is not too big.
[0014] Thinking about the high incidence of bacterial, micotical
and viral illness in the gynecological area, and that some of these
are involved in the feminine cancer etiology, and that in many
cases the practice of methods using cauterius, radio frequency or
laser, is necessary, generating smoke and gases that can be sources
of contamination, the speculum described has in the upper sheet's
internal face three cuts (to a certain distance each one) separated
one of another by a certain distance and internally connected by a
pair of channels designed to evacuate them through a special
vacuum, also improving the visibility, having as a result a less
time investment.
[0015] The cut's surface of the speculum proposed by me, is big
because of it semicircular form, and because they are distributed
along of the upper sheet and bilaterally and internally connected
will have a bigger absorption surface, a bigger utility and
effectiveness.
[0016] It also has three cuts on the lower sheet's internal face
that will drain the blood and liquids originated from the surgery
area, whether vaginal, cervical, or when they practice uterine
endoscopes, making faster proceedings, avoiding the drying and
cleaning at intervals of the surgical area, specially in these last
ones, where large amounts of liquids are used. To make the speculum
use faster and comfortable, some bottoms have been designed, which
by pressing make the opening and closing of it easier.
[0017] The ideal would be a prototype of speculum, which would have
included all the necessary mechanisms for examination and
gynecological surgery through the vaginal tract, and easily
disposable later, because this area sometimes is highly
contaminated by sexual transmission illnesses, bacteria, fungus,
and virus, some of these involved in the feminine genital cancer
etiology.
[0018] The prototype of the disposable speculum created by me,
offer and join these advantages.
BRIEF SUMMARY OF THE INVENTION
[0019] It is about a disposable speculum with included light and
complementary mechanisms for examination and gynecological surgery;
which offers positive advantages compared with the ones which are
actually used in this health branch.
[0020] As a gynecological medical doctor, I am concerned for
practicing an excellent exam, looking for the patient's and our
comfort, which will have optimum results that will change the
preconceived negative mentality of our dear patients for this type
of exams and procedures, making them more agile and that using the
specula is not traumatic, I decided to propose a prototype of a
plastic transparent disposable speculum, which includes several
requirements for such purposes.
[0021] The speculum upper sheet external face is convex, of flat
surface and having rounded edges to avoid pinches, which are so
common with the disposable speculum that does not have delicate
edges. The internal face of the same sheet is concave and has three
semi-circulars cuts at a certain distance between them, and
connected through a pair of lateral internal channels which end in
upper right area of the proximal, which will serve to evacuate with
a special vacuum (available in the market) the smoke and gases
produced when any kind of gynecological surgery through the vaginal
tact is practiced, where cauterys are used, monopolar or bipolar
electrodes, radio frequency or laser, protecting de medical doctor
and near staff of possible contamination, making the procedure
easier and shorter and offering a better visibility.
[0022] The external face of the lower sheet is convex with a flat
surface and has it also has its rounded edges. The internal face of
the same sheet is concave and has three semicircular cuts at a
certain distance amongst themselves, connected between them by an
internal oval, flat channel which ends in the lower end of the
descendent branch of the sheet where it becomes in to a round
channel through which the blood produced on the surgical area is
evacuated through a vacuum used for this procedures, making them
easier and faster and avoiding the drying and the cleaning of the
places where the blood is accumulated. If this end is not connected
to a vacuum, it can be connected to a container through a hose and
the blood will flow by gravity. The vertical branch or upper
sheet's handle has some prongs in it and they fit in the vertical
branch or lower sheet's handle which has some foremasts where the
saw prongs are inserted when the specula is opened to expand the
visual and examination field. In order to reduce the specula's
opening, pressure is made on a button that forces the prongs to go
out and separate from the foremasts sliding the vertical branch of
the upper branch into the lower sheet's vertical branch; to close
the speculum and remove it without discomfort pressure has to be
made over another button that unlocks the upper sheet.
[0023] Joined with the previous, and in order to optimize the
examination area or surgery area visibility, on upper sheet's
internal face, centrally and in the space between the two first
cuts, there is a small light bulb which, given it nearness to the
surgical area, will give clarity and because of its localization,
will not interfere on the surgical procedure. The light bulb is
protected to avoid damages with the instruments and has a thermal
isolation to prevent the specula's upper sheet to be heated because
it would create injuries on the vaginal mucous.

[0068] 24. Back cut of the Handle of the back sheet.
[0069] 25. Bi-lateral cuts on the handle of the lower sheet.

handle going out of its place.
[0074] 30. Plug for the blood drainage.
[0075] 31. The drainage plug's cap.
[0076] In many cases the gynecological examination turns difficult
because a part of the consulting and gynecological pathology and
the majority of the gynecological surgery through the vaginal
tract, entails genital bleeding which will interfere in the
suitable observation, making necessary cleaning and drying the
surgical or examination area with certain frequency and depending
of the intensity of the bleeding, many times it flows through the
speculum lower sheet towards the outside, contaminating the table
and everything else and making the process difficult and delayed.
The same happens when diagnosis procedures are practiced
endoscopies or surgical endoscopics of the uterus, in which liquids
have to be used to expand the cavity and to be improve the
visibility. This also happens in procedures where the cauterys, the
electrodes monopolares, the radio frequency or the laser is used;
in the surgery area smoke and gases are generated that difficult
the visibility and, which is worst, when there are virus involved
in the pathology to be treated, some of them related with feminine
genital cancer, creating microparticle for them, that can to
contaminate to the medical doctor and the staff around.
[0077] Thinking about the previous matters, I have created a
prototype of disposable speculum which not only will facilitate the
examinations and medical procedure and/or surgical gynecological,
but it also avoid contamination and it will make the process less
length, which in a given moment are traumatic for the patients.
[0078] The disposable speculum mentioned, is of transparent plastic
material and consist of upper sheet (1), mobile, with the external
face of convex shape, of flat surface and round edges; its internal
face is concave and has three cuts (2): front, middle and back,
semicircular, joined between them by a pair of laterals internal
channels: right (3) and left (4) which end in a plug (19) which
goes to a special vacuum, which will drain the smoke and gases
produced in the surgery area. The upper sheet also has a right
lateral extension (9) obliquely oriented and downwards in an angle
of 30 grades approximately, that is used to open the speculum and
to move separate the vagina's walls in order to practice a complete
examination of them, of the cervix and the fornix. The lateral
extension has a space or opening (9a) where a mobile safety bar
shaped goes through (10), which comes from the lateral middle part
of the vertical branch of the upper sheet. That bar has in its
lower flat face semi-curved prongs (10A) with their tips forward,
which are inserted in a space (11A) of the lateral extension
located in the back part and lower to the opening pushed by a
plastic spring (11) which is in of the cylinder (12) located in the
upper back part at the opening of the same
[0079] extension.
[0080] The vertical branch or back handle (5) of the upper sheet
has a fork shape. Its upper end (8A) articulate for both sides to
the proximal end (8) of the upper sheet to give it mobility when
opening and closing the speculum. The lower part of that handle has
handleshape, being its back branch shorter and which has saw prongs
(6) at both sides with their tips downwards, which insert in a
foremasts (28) when a button, for this purpose, is pushed forward,
upward and downward.
[0081] The upper middle of the fixed vertical branch or front
handle (23) of the lower sheet has semicircular shape and is hollow
to hold the back handle. (5) It has a back cut (24) where it is
pulled in and slides the back handle's button (7). Internally at
both sides of the cut has some foremasts (28) where the saw prongs
(6) of the back handle go. Bilaterally there is a cut (25) where
partially the fork of the back handle is inserted (5). The lower
part of the front handle has an elbow shape (27) where the ring
finger is placed facilitating its handling and avoiding
contamination. In the anterior wall of this handle and internally
the channel goes down (22) to evacuate the blood and liquids which
come from surgery area or from the examination.
[0082] To close the upper sheet pressure needs to be made upwards
on the button shaped end of the safety devices (10) and it will
close by the action of the muscles of the vagina, the anal and
perineal elevators, controlling with the thumb finger the gentle
closing, because both buttons, that is, the one for opening the
speculum (9) and the and the one of the safety device (10) are
close one of another. All the buttons have concave shape, and they
adjust itself better to the thumb finger to-press to open or to
close the speculum.
[0083] The low sheet (20) is convex externally, with flat surface
and rounded edges. Its internal face is concave and has three cuts
(21): frontal, media and back, semicircular, joined between them by
a central internal oval flat channel (22) which goes down by the
frontal side of the vertical branch or handle (23) of the lower
sheet; and by its lower rounded end (30) the blood on liquids will
be evacuated from the surgical area or from the examination, when
this channel is connected to a vacuum or by gravity to a small
bottle. This end has a cap (31) for when it is not used to
drain.
[0084] Looking for a optimum lighting, the internal face of the
upper sheet has a small light bulb (13) centrally located between
the two firsts cuts, with a thermal isolation (14) to avoid
injuries on the vaginal mucous when the sheet becomes warm and to
keep the light bulb protected (15) of damages that could happen to
it with the instruments. The internal face in the place in front of
the light bulb has a reflected cover (16) with aluminum (a metal
covering vacuum technique with aluminum), what has effect on a very
good lighting. The light bulb receives through a plug (19) the
electric current feed by a source of conventional light.
